UNITED Y STATES PATENT OFFICE.

JOHN H. THOMPSON, OF EDNA, CALIFORNIA.

CULTIVATOR AND WEED-CUTTER.

SPECIFICATION forming part of Letters Patent No. 698,586, dated April29, 1902. Application filed January 28, 1902- Serial No. 91,548. (Nomodel.)

To aZZ whom it may concern:

Be it known that 1, JOHN H. THOMPSON, a citizen of the United States,residing at Edna, in the county of San Luis Obispo and State ofOalifornia,have invented certain new and useful Improvements inCultivators and Weed- Cutters; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention, which relates to cultivators, has for its object theproduction of an improved machine constructed on simple and durablelines for use in the cultivation" of beets, beans, and the like and inthe removal of weeds.

The nature of the invention will be readily comprehended, referencebeing had to the following detailed description and to the accompanyingdrawings, in which Figure 1 is aperspective view of a cultivator andweed-cutter embodying my invention. Fig. 2 is a top plan view. Fig. 3 isarear elevation. Fig. 4=is an enlarged vertical sectional view on line 44 of Fig. 2.

Referring to the drawings by letter, A denotes the beam, extendingforwardly of which is the tongue I) and to the rear of which andparallel therewith is a second beam 0. The beam A is preferablyconstructed of a solid rod a and spacing-sleeves ct a, and the beam 0 ispreferably also constructed of a solid rod 0 and spacing-sleeves c" c.The beams are rigidly connected together by bars perforated to receivethe rods and held in proper rela-' tion by the spacing-sleeves. The endbars at d are secured by nuts 6 c, screwed on the threaded ends of therods.

(1 cl are the central bars,which are extended beyond the beam A to formthe support for the tongue 17.

d d areintermediate bars extended beyond the beam A to provide bracesfor the tongue.

6 e designate handles for guiding the machine, the lower ends of whichare perforated to receive the rod a and which flank the bars (1 and theupper ends of which are connected together bya rod f and sleeve f andare supported by arms g g, secured to the rodf by The blades aresupported from the rear beam 0 and are of approximately U form. From thecutter portion g of each blade extend upwardly supporting-arms g g whichare perforated to receive the rod 0, and said blade is braced by arms 72h, bolted to the arms g and to the bars which connect the beams. Thebars are provided with a series of holes t' i, which receive thesecuring-bolts t" of the arms h, whereby the blades are adjustable tovary the inclination of the cutter portions g.

The forward edge of each of the cutter portions, as well as the lowerportions of the supporting-arms 9 are beveled to provide cutting edges,the bevel of the cutter portion be- The inner blades G G are each ofsuch width as will occupy the entire space between two rows, and theouter blades G G are preferably of such a width as will occupy'one-halfofthespace beyond the outer rows.

In practice, the machine being in motion,

the blades enter theground to the desired idepth, looseningthe earth andcutting the weeds at or near the roots. The blades by reason of theirpeculiar form meetwith but slight resistance, the blades being presented'edgewise, so that little power 'is required to draw the machine. The"machine is very light in weight; but the construction employed possessesstrength, rigidity, and durability.

By reason of the construction employed the machine may be knocked downand I packed into small compass for transportation.

I claim as my invention- 1. In a machine of the class described, the

combination of a beam, blades secured to the beam each blade having aflat cutter portion,

- arms extending from the cutter portion and secured to the beam, andbrace-arms for the blades.

2. In a machine of the class described, the combination of a beam,U-shaped blades secured to the beam each having a fiat cutter portion,and brace-arms adjustably connecting the blades to the frame whereby thecut-.

ter portions may assume various degrees of inclination.

3. In a machine of the class described, the combination of a forwardbeam, a rear beam secured to the forward beam by bars, U- shaped bladesdepending from the rear beam, spacing-sleeves on the beams securing thebars and blades in position, nuts on the JOHN H. THOMPSON.
